Looking ahead of the 1990s, a very rapid growth of the global satellite communications industry into personal communications and emerging mobile satellite networks such as Personal Communication System (PCS) and Mobile Satellite Services (MSS), Low Earth Orbit (LEO) satellite systems, Global Positioning System (GPS) navigation, and other direct satellite services could be observed. Towards the end of the 1990’s, LEO satellite services were launched and growth depended on competitive factors. Conventional Fixed Satellite Services (FSS) and Maritime Mobile Satellite Services (MMSS) have been growing steadily but not as they had before, check this link right here now.
The fixed satellite services were severely challenged by the optical fibre cables, which now formed a greater part of this communications revolution throughout the world. The fibre optics cables carried very high data rates, comparable to High Dynamic Range (HDR) graphics which require more than 155Mb per second of data transmission, which required excellent signal conditioning. Fibre optic cables have better performance than satellites, with significantly less transmission time delay. This was a time when satellite networks, for example T1=1.5Mb per second, had to prove their superiority over HDR applications and networking. In fact, a T-1 line consists of 24 individual channels, each supporting up to 64Kbits per second data rate. The benefits include wide area coverage, distance insensitivity, versatility, capabilities for multiple accesses and destinations, and efficiency. While much of HDR traffic, such as multi-channel telephone trunks, will be transmitted from satellites to cables via fibre optics cables, new opportunities are opened up for HDR satellites to carry HDTV picture signal delivery, as well as supporting the emerging Distributed High-Performance Computing (DHPC) sector. HDR satellites had to be built and deployed commercially to gain access to the market for this application.
By now it was clear that the world of satellite communication was rapidly changing, and there were threats to fixed satellite services, while new opportunities were opening up in mobile, broadcast and personal services. Today, the role of the United States in satellite communication is being questioned, though it was certainly the pioneer in such technologies and was an agent in past changes.
There are reasons why a grim evaluation of US’s future in satellite communications technology has been made.
